Man In The Middle on Aws

How Man In The Middle Manifests in Aws

Man In The Middle (MITM) attacks in AWS environments typically exploit the trust relationships between AWS services and their network endpoints. The most common AWS-specific MITM vectors involve intercepting traffic between your application and AWS service endpoints, particularly when using unencrypted connections or when DNS resolution is compromised.

AWS services communicate over HTTPS endpoints by default, but developers often make critical mistakes that enable MITM attacks. For example, using AWS SDK clients with custom HTTP clients that disable SSL verification, or connecting to AWS services through proxies that terminate TLS connections. Another common pattern is using HTTP instead of HTTPS when configuring AWS CLI or SDK clients, which exposes traffic to interception.

Consider this vulnerable AWS SDK pattern:
